JEHU BRAINERD, OF CLEVELAND, OHIO.

IMPROVEMENT IN DEPILATING AND BATING SKINS.

Specification forming part of Letters Patent No. 35,293, dated May 20,1862.

To all whom it may concern:

BeitknownthatLJEHU BRAINERD,ofOleveland, in the county of Ouyahoga andState of Ohio, have invented new and useful Improvements in Depilatingand Batin g Hides and Skins; and I do hereby declare that the followingis a full and complete description thereof.

The nature of my invention relates to a combined depilatin g and. bating process by means of which some two or three weeks time is saved infitting'skins and hides for the tan, besides a saving of expense andlabor, and the dispensing wholly with the solution of hens or pigeonsdung, commonly called the hate, the skins and hides being left in a softand flacid condition, and affording a better quality of leather thanwhen unhaired and hated in the common method.

Green skins need no preparation except the usual operation of fleshing.Salted or dried sulphate of .soda in water and thoroughly incorporatethe same with the lime-andsulphur paste before described, and it isready for use. The depilating-vat is filled with clean water, andone-sixth of an ounce of the paste (calculated dry) is added for eachgallon of water the vat contains, and thoroughly mixed, and it is readyfor use, and as many skins or hides may be immersed therein as willfreely float. They should be handled as many as three or four timesduring the first twelve hours, and the temperature of the liquid shouldrange from 60 to 80 Fahrenheit. Usually for light skins twenty-fourhoursimmersion will be found sufficient. Heavy hides, especially thosethat have been salted or dried, will require more time. The same liquormay be strengthened for another pack; but I prefer to prepare anew foreach pack. After the skins are unhaired they should be soaked in cleanwater and worked upon the beam. The above-named proportions may bevaried; but one-sixth of an imnce will generally be sufficient for eachgal- What I claim as my improvement, and desire to secure by LettersPatent, is-

The herein-described compound for depilatin g and hating hides andskins, the same being combined in one operation, as specified.

J. BRAINERD.
